TO ALL WHOM IT MAY CONCERN:

Be it known that I, JACOB H. SHILEINER, of Camp Hill, Cumberland county,Pennsylvania, have invented a new and useful Improvement-inGrain-Drills; and I hereby certify the following to be a full,clear,\and

exact description of the same, reerencebeing had to the annexeddrawings, making a part of this specification,

and to the letters of reference marked thereon.

The nature et' my invention consists -in combining apeculiarly-constructed device for scattering or distributing the seed orgrain, with the boot, orconveyer-pipe, substantially as hereinafter setforth. A In the drawings- I Figure 1 is a vertical section of the lowerend of the boot, or seed-conveying pipe, showing the improved device inproper position. y

Figure 2 is a transverse section of said boot, immediately above thedevice. vFigure 3 is a view in perspective of a part of the improvedscatterer, or distributor, styled the contractor. In figs. 1 and 2, A.represents the boot or conveying-pipe. This is made of a proper lengthand size, and is given the form or contour substantially as shown in thetransverse section in lig. 2. -At a proper distance from its lower end,upon the inside of said boot A, thc'contractor B is placed. Saidcontractor is made in the form of an inverted frustum of a cone; it ishollow, and open at both ends; its upper end is made of such relativesize to the inside of the boot, as to neatlyt it, a shoulder of propershape being formed upon the inner surface of the boot to accommodate it,as seen in iig. 1. The said contractor Bean either be cast of the samematerial and in position in the boot, or be made-separately, andattached by any suitable method. In

fig. 1 it is shown as being made separate, and held in place by pins orrivets.

Upon the inner surface .of the contractor B, a cross-bar, a, is placed,or rigidly fastened, as seen in fig. 1. This bar is so constructed thatits upper side shall form anedge, so as to prevent grain or seed fromlodging or being impeded in its passage. v p i The cross-bar a isfurnished with a boss, or rounded-enlargement, at .its centre, midwaybetween `the walls of the contractor B. Said boss has a hole madethrough it, of a proper size to receive the bolt or stud c that projectsfrom the apex or crowniof the bell-shaped seed-scatterer C. Saidscatterer C is given the form, subv stantially as shown in iig. 1,and,as before stated, has a bolt or stud, c, projecting from itsupper'end, that passes through the hole formed for its reception incross-bar a. .It is secured in said position by a nut, e. At

the rear of the contractorB,lf1-om its lower end, a piece, b, of`peculiar form, shown ,in figs. 1 and 3, projects downward, and bearsagainst the side of the bel shaped distributor C. Said piece 6 isintended to deflect or throwV forward thegrain or seed that'falls on therear of the scatterer G,`as such grain, if this provision were not made,would be liable to be improperly covered. The piece Z also serves as asupport or brace to the seattcrer C.

The boot and'also the distributor and contractor are made of cast iron,or other suitable material.

Figure 3 shows a front view of thc contractor B, and also'of the braceor deector b.

'The several parts of the device being placed together in properposition, as shown in iig. 1, the operation is as' follows: y

,2, The grain being fed into the boot A by the mechanism usuallyemployed in grain-drills, falls down said boot, and is. gathered orconccntratcd,'by the contractor B, toward the centre of the boot, sothat it falls directly upon thc crown and'sides of the bell-shaped'distributor C, and is by it evenly distributed over the surface of theground immediately under it, the guard or brace b preventing it fromflying in the rear too far,

and thus be left uncovered. The grain after it is' sown is covered byany suitable attachment that will pperly effect the purpose.

I am awarethat grain-scattering or spreading devices have already beenpatented, and are in use. But they are defective, from the fact that inusing-the machine upon a hill-side, the grain, in the operation ofsowing it, falls almost entirely upon the lower side of the scatterer orspreader, and is of course imperfectly distributed.

vThis effect I entirely overcome by the peculiar action of thecontractor-B, in combination with the bell-shaped scatteer C, as'thegrain will always be concentrated upon the crown of the scatterer C, nomatter what degree of inclination the feedpipc or boot A assumes, andwill, therefore, be as evenly and perfectly sown upon the side of a.hill as upon level ground.

I do not d esire bioadly to claim the general use of ascattering-device, conical or other shaped, when used alone; but

What I do claim as new, of my invention, and desire to secure by LettersPatent of the United States, s-

The combination and arrangement of' the boot A, with the contractor Band distributor C, when said distributei is sustained in position,substantially as shown and described.
